Subject: macvlan: fix memory hole in macvlan_dev
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=5e54b3c1202765ae62de24a160f1eaf6b0ebf9d4;p=openwrt%2Fstaging%2Fblogic.git

macvlan: fix memory hole in macvlan_dev

Move 'macaddr_count' from after 'netpoll' to after 'nest_level' to pack
and reduce a memory hole.

Fixes: 88ca59d1aaf28c25 (macvlan: remove unused fields in struct macvlan_dev)
